In this section, we present some related works on CTI sharing and the integration of blockchain platforms for CTI sharing and provide a discussion on the findings of this chapter. Several studies discuss the importance of CTI sharing in information security and general computing systems [1]} [2]} [3]} [4]}. However, most of them discuss CTI sharing from the lens of traditional centralised computing approaches. Subsequently, few publications considering how blockchain-based approaches can overcome existing challenges are present in the literature. In this section, we aim to discuss the contributions of several publications that outline challenges associated with CTI sharing.
